WEP and 13 characters for 128 bit WEP. You must enter a separate
string for each of the 4 Keys. You can leave a string blank provided
this Key is not selected as the Active Transmit Key.
■
Passphrase - This is another common method and similar to the 3Com
Encryption string. In 64 bit WEP, the passphrase will generate 4
different keys. However, in 128 bit WEP, this method only generates 1
key which is replicated for all 4 keys. The passphrase can be up to 31
characters long and may contain any alphanumeric characters.
Select from the drop down list the key generation method you wish to
use. If you have other wireless products choose the scheme that is
compatible with these, then enter the appropriate information.
If you encounter any difficulty when you enable WEP ensure that you
check that each key on your wireless computer is exactly the same as
each key on your Access Point. In other words, Key number 1 on the
Wireless computer must have the same Hex number as Key number 1 on
the Access Point, Key 2 on the Wireless computer must match Key 2 on
the Access Point and so on.
The Active Transmit Key selects which of the 4 Keys the Access Point uses
when it transmits. You can change the selected key periodically to
increase the security of your network.
Some wireless adapters have only one key available on their WEP
configuration page. If this is the case ensure it is the same as Key 1 on the
Access Point and that it is selected as the active transmit key.
Connection Control This screen allows you to determine if all Wireless PCs or just authorised
Wireless PCs can use the Access Point. Select Connection Control to
display the screen shown in
